Rare Earths Americas’ Homer project: footprint growth and HREO upside for mine planners
Reviewed by Joe Ashwell
First reported on MINING.com
30 Second Briefing
Rare Earths Americas has expanded the mineralised footprint at its Homer-A ionic clay rare earth project in Goiás, Brazil by over 60% to about 3.5 km², with the main zone now extending 4.3 km and remaining open. Assays from 20 holes within the primary geochemical anomaly show 19 above cut-off, while drilling on the south-eastern margin has returned heavy rare earth oxides with dysprosium-terbium oxides reaching up to 8.7% of total rare earth oxides plus scandium. Only 22 of roughly 180 planned holes have been assayed, with 11,800 m of a 15,000 m 2026 programme already drilled and a maiden resource targeted for 2027.
Technical Brief
- Eight additional drill holes at Homer-A triggered the latest footprint expansion announcement.
- Homer-A is one of three 100%-owned exploration targets within the wider Homer project in Goiás.
- Heavy rare earth enrichment occurs across multiple holes and intervals, not as isolated single-sample spikes.
- Only 22 of roughly 180 planned 2026 drill holes have returned assays so far.
- About 11,800 m of the planned 15,000 m 2026 drilling programme had been completed by 30 October 2026.
- Rare Earths Americas also controls ionic clay projects elsewhere in Brazil plus a monazite-rich sands project in Georgia, USA.
- Market reaction has been muted to negative, with REA’s New York–listed stock down 10% on the news.
Our Take
Rare Earths Americas already features in our coverage for ionic clay testwork at the Alpha project in Bahia, so the Homer heavy rare earth oxides footprint in Goiás suggests the company is building a multi‑asset Brazilian rare earths platform rather than a single‑project story.
Brazil’s recent designation of rare earths as a high‑priority critical mineral means a project like Homer in Goiás is well placed to benefit from streamlined federal support mechanisms flagged in that policy, which can materially shorten timelines for 100%-owned exploration plays.
With dysprosium and terbium explicitly in focus at Homer and also highlighted in REA’s Alpha testwork, the company is clearly targeting the magnet rare earth segment, which in our database tends to attract more strategic interest from OEMs and governments than light-REE‑dominant deposits.
